Vitiligo: Overview Vitiligo: This skin disease often forms on both sides of the body as shown here on the knees. Vitiligo (vit-uh-lie-go) causes the skin to lose color. Patches of lighter skin appear. Some people develop a few patches. Others lose much more skin color.
Removing and inspecting spark plugs tell you a lot about how well the engine is running and what may be causing problems. All spark plugs should be removed and checked every 30,000 miles - even if your BMW is low maintenance - you're told to change spark plugs at 100,000 miles. This prevents the plugs from seizing in the block, causing expensive repairs down the road. Always note which plug came from which cylinder.
Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. We recommend that you follow the oil and filter change frequencies shown in your owner's manual, especially during the warranty period. With the high-performance reserves of Mobil 1, you can have the confidence to go the full mileage or time frame recommended by the vehicle manufacturer.
